As one of the wettest places on Earth, the Hawaiian island of Kauai is bursting with lush scenery, dramatic mountains, verdant valleys, and breathtaking waterfalls.
There are several waterfalls on the island that are easily accessible, whether you want to admire them from a roadside overlook or prefer a hiking trail. However, many other falls are in remote locations and are best seen on a helicopter tour.
Opaekaa Falls, Wailua
This 151-foot waterfall near Wailua River State Park is just a short drive from Lihue and ranks among the island’s most popular thanks to its easy access. Visitors can follow a paved path to a scenic lookout or simply take in the view from the overlook along Kuamoo Road/Route 580. Opaekaa means “rolling shrimp,” named after the shrimp that inhabit the pool beneath the falls. Hiking down to the base is treacherous and only possible via an unmaintained trail, so the best way to experience Opaekaa Falls is simply to enjoy it from above. If you want a waterfall hike, you’ll find plenty more options on this list.
Waipo’o Falls, Waimea
Head to Waimea Canyon to discover this waterfall along one of the top hikes in Kauai. Waipo’o Falls cascades 800 feet and is visible from Highway 550, but those seeking more adventure can hike to the top via the Waipo’o Falls Trail. This 3.2-mile round-trip trail is a popular, moderately challenging outing that’s even suitable for families. The falls are most impressive during the rainy season. Note there is no trail to the base of the waterfall. For a closer look at Waipo’o, consider booking a helicopter tour of Waimea Canyon.
Hanakapiai Falls, Waineha
The hike to Hanakapiai Falls is challenging, but it’s a favorite among adventurous hikers. You’ll take the coastal Hanakapiai Trail from Ke’e Beach, winding through rocky switchbacks and slippery mud to Hanakapiai Beach. The beach itself is rugged with rough surf—swimming is usually too dangerous. From here, it’s another two miles to the falls, following the Hanakapiai Stream to the emerald pool beneath the 300-foot cascade. After the trek, reward yourself with a freshwater swim in the natural pool. Since this Napali Coast hike is particularly popular, start early to avoid crowds.
Wailua Falls, Lihue
Another easily accessible highlight is Wailua Falls, found north of Lihue. This double waterfall is often known as the “Fantasy Island” falls, featured in the opening credits of the 1980s TV show. Take in the views from the parking lot or take a short but steep walk for a closer look. The falls are created by the split in the Wailua River before plunging more than 100 feet. You can view these waterfalls any time of year, but if you’re after a rainbow, visit in the morning when the sunlight creates the perfect conditions.
Hanakoa Falls, Hanalei
Located along the Napali Coast, Hanakoa Falls is accessed on foot via the Kalalau Trail. Dropping 1,000 feet down the mountainside, the falls tumble over several tiers—hikers can’t see the entire flow at once, but the sections visible from the trail are well worth the six-mile journey. Since it’s about halfway along the Kalalau Trail, Hanakoa Falls is remote and mostly visited by experienced hikers. Anyone wishing to reach Hanakoa Falls will need to obtain a day-use permit from the Lihue government office.
Ho’opi’i Falls, Kapa’a
Located on Kauai’s east shore near Kapa’a, Ho’opi’i Falls consists of two distinctive falls: Upper Ho’opi’i and Lower Ho’opi’i. Offering a short walk through Kauai’s lush canopy forest, this hike is a favorite, especially for first-timers. In just a two-mile round trip, you’ll get spectacular views. Those hoping to swim in a waterfall pool should head to Upper Ho’opi’i, which features an inviting swimming hole and a spot for cliff jumping. Lower Ho’opi’i Falls is also worth a visit; its 30-foot drop was featured in the blockbuster film “Jurassic Park.”
Uluwehi Falls, Wailua
Also known as Secret Falls, Uluwehi Falls lies in the Wailua River Basin on Kauai’s eastern side. Reaching Uluwehi is more adventurous than some of the other accessible waterfalls here, since you begin by paddling up the Wailua River. Because the journey can be challenging, guided tours are available. Kayak for about two miles, then set off on a relatively easy, but often muddy, hike to the falls. This 100-foot waterfall is well worth the 50-minute paddle and 30-minute trek. While it’s called “Secret Falls,” don’t expect solitude—this is a popular hike on the island.
Weeping Wall Falls, Mount Waialeale
The magnificent falls that make up Mount Waialeale’s Weeping Wall are the least accessible on this list. These cascades are located on the island’s tallest mountain, one of the wettest places in the world. The easiest way to view them is by helicopter, but there is also a tough trail leading to a waterfall pool known as the Waialeale Blue Hole Falls Trail. If you plan to hike, expect wet and muddy conditions. The 4.9-mile Blue Hole hike brings you to the lush, green mountain walls with countless waterfalls streaming down.
